[Monotone-devel] change_set.cc:342: invariant 'I(isect.empty())' violated

[Peter Simons]

While propagating from one branch into another, I got this error:

 | [...]
 | executing external 3-way merge command
 | monotone: fatal: std::logic_error: change_set.cc:342: invariant 
'I(isect.empty())' violated
 | monotone:
 | monotone: this is almost certainly a bug in monotone.
 | [...]

monotone 0.18 (base revision: d8f07697467b0f4edca8c766d61d2dfa708dabd9)

The debug output produced by Monotone doesn't seem very
helful. The last few lines are simply:

 | [...]
 | skipping preserved directory 13285 : 'src/blastd/corba'
 | skipping preserved directory 13286 : 'src/blastd/java'
 | skipping preserved directory 13287 : 'src/blastd/newsexpress'
 | change_set.cc:342: invariant 'I(isect.empty())' violated
 | db.execute("ROLLBACK")

As usual, I can't share the database. :-(

Maybe this helps nonetheless. If there's anything I can do
to produce more data to figure out what happened, just let
me know.
